Patency Check Compatible Check Valve And Fluid Delivery System Including The Patency Check Compatible Check Valve

The check valve includes a housing body and a valve member. An actuator is associated with the valve member or housing body. The housing body defines a flow passage and an inlet port and an outlet port each communicating with the flow passage. The housing body includes a seal seat in the flow passage between the inlet port and outlet port. The valve member is disposed in the flow passage and is adapted to engage the seal seat. The actuator may be operatively connected to the valve member to place the valve member in an override position permitting bi-directional fluid flow through the flow passage. The valve member may be a cantilever valve member responsive to fluid flow in the flow passage. The valve member may have multiple states or positions. The actuator may be a bypass actuator selectively placing the inlet port in fluid communication with the outlet port.
